Global Future of the Environment
Responding To: The Challenge of Climate Change
Feeling Under the Weather? The Impact of Climate on Health and Our Economy
No person, community, or country is immune to the health impacts of climate change.
Until fairly recently, the impact of climate change on health was not a major focus in the scientific community. However, the evidence is mounting that life-threatening consequences are arising from the climate changes that we are experiencing at an accelerating rate. The scale of health risks is on par with the enormity of climate change and can vary considerably based on geographic region. For example, as the earth warms, we are experiencing seasonal changes with earlier springs and later fall frosts leading to increased allergies in the Midwest region of the U.S. from an extended pollen season. In the southeast, this warming has led to an expansion in the ranges of mosquitoes carrying dengue, West Nile, and malaria.
Several high profile reports have underscored the importance of climate changes on health. The World Health Organization predicts that climate change will cause approximately 250,000 additional deaths per year between 2030 and 2050 primarily from malnutrition, diarrhea, malaria, and heat stress.
The Intergovernmental Panel on Climate Change projects substantial increases in “ill-health” resulting from climate change including:
- Risk of injury, disease, and death from intense heat waves and wildfires
- Reduction in food production with risk of under-nutrition
- Reduction in work production
- Food-borne diseases
- Water-borne diseases
- Vector-borne diseases
Limited but emerging data indicate that health, social and economic costs of climate change are vast, with one study estimating health costs of six climate-related events at approximately $14 billion, which is consistent with costs from other weather and climate related disasters.[7-8]
The U.S. EPA estimates that implementation of the Clean Power Plan will lead to significant public health benefits from a reduction in premature deaths, asthma attacks in children, heart attacks, hospital admissions, and missed school and work days with benefits worth an estimated $34 billion to $54 billion per year in 2030.
Climate change is ultimately about health. It is imperative that climate-related health impacts are seriously considered as we continue to adapt to the effects of climate change, evaluate the overall economic losses as a result of health impacts, and strive to mitigate further damage.
Dr. Laura Anderko, Ph.D. RN holds the Robert and Kathleen Scanlon Endowed Chair in Values Based Health Care at Georgetown University School of Nursing & Health Studies and serves as director of the Mid-Atlantic Center for Children’s Health and the Environment (Region 3’s Pediatric Environmental Health Specialty Unit). Dr. Anderko was honored by the White House for her work in climate change and public health.
